THE YF SERIES FROM WALL INDUSTRIES
The YF series of DC/DC converters performs over an ultra-wide input voltage range (2:1 & 4:1), providing indefinite
short circuit and overvoltage protection. The series’ design technology allows up to 20 watts of output power from a
1.60” x 2.0” x 0.40” case. These current mode control forward converters are designed for improved transient response
and reduced stress on switching components and do not require external input filtering, making it a preferred source
over industry alternatives.
SPECIFICATIONS: YF SERIES
All specifications apply @ +25 C ambient unless otherwise noted.
